[GRASS-user] libgrass_gis.6.3.0.dll

Dear Grass Experts

I recently downloaded the Windows version of 6.3.0, to run under XP, and it looks like it will be useful to me. But I keep seeing an error which says that file

libgrass_gis.6.3.0.dll

cannot be found. This happens if I navigate to

C:\GRASS\bin

and type, for example,

g.version

The dll exists all right. It is in

C:\GRASS\lib

so I’m struggling. Is there a crucial environment variable that I need to reset?

Hi Christopher,

I recently downloaded the Windows version of 6.3.0, to run under XP, and it looks like it will be useful to me. But I keep seeing an error which says that file
libgrass_gis.6.3.0.dll cannot be found. This happens if I navigate to C:\GRASS\bin and type, for example, g.version

to use GRASS you cannot just type the commands (executable files) from the directory where they are located. You need to start GRASS first (from DOS or MSYS command line. or using the TclTk or Python GUI).

The dll exists all right. It is in C:\GRASS\lib so I'm struggling. Is there a crucial environment variable that I need to reset?

Yes. All the needed variables are already set in the grass63.bat file that is called when you launch GRASS from the GRASS group menu or from the desktop icon.
Read the release notes on about launching WinGRASS: http://grass.osgeo.org/grass63/binary/mswindows/native/README.html#Launching%20GRASS

Regards,

Marco

There are several environment variables which need to be set in order
for GRASS modules to work. This is done by the grass63.bat script.

GISBASE needs to be set to the root of the GRASS installation, i.e.
C:\GRASS in this case.

PATH needs to include $GISBASE\bin and $GISBASE\scripts, and on
Windows, $GISBASE\lib (other OSes have a separate variable for
libraries).

GISRC needs to be set to the path to a file which contains several
configuration settings (by default, the file is $HOME\.grassrc6).

GIS_LOCK needs to be set in order for g.mapset to work (the actual
value doesn't matter).

GRASS_SH needs to be set to the path of a Bourne shell in order for
scripts to work.

Various modules may need other environment variables, e.g. GRASS_PAGER
may need to be set to the name of a pager such as "more" or "less".

A (mostly) complete list can be found in the docs/html/variables.html
file within the GRASS installation.
